I was corrected by Dan from Belt Talk. This belt is made by Dave Millican, but it's WWE's design. Really wish they had just handed the reigns over to Millican, but there's no doubt you know who the champ is representing.
Never saw those proposed belt images before. They could have made the last one work, I guess. Honestly, I think if the background on the new belt's main plate wasn't black, but maybe silver, and they added an eagle to the top, it would look pretty good. The huge W would still pop, since it's gold, but it wouldn't assault the eyes.
And the eagle could be like the one they had on the older tag belts. The one spread out at the top of the belt.
